An automatic qoe-aware management device based on sdn

Abstract

The invention discloses an SDN-based automatic QoE sensing management method and apparatus. The method comprises: an experience score in user feedback information of a user selection service is obtained; according to the experience score and a QoS parameter of the user selection service, MOS calculation of the user selection service at different transmission paths is carried out; and then a comparative analysis is carried out on the calculated MOS values and a preset QoE threshold of the user selection service to determine whether a risk of QoE degradation exists, so that the infrastructure resources of an underlying network are adjusted automatically to avoid QoE degradation.

Description

technical field

[0001] The invention relates to the technical field of power grid security and stability control communication, in particular to an SDN-based automatic QoE perception management method and device. Background technique

[0002] QoE (Quality of Experience) refers to the comprehensive subjective experience of users on the quality and performance (including effectiveness and availability) of equipment, networks, systems, applications or services. Through QoE scoring, operators can evaluate users' experience of network services in order to optimize the network. From users to the network, it is a top-down approach.

[0003] QoS (Quality of Service) refers to a network that can use various basic technologies to provide better service capabilities for specified network services. It is a security mechanism for the network and is used to solve problems such as network delay and congestion. a technique. The current network architecture is mostly based on the TCP / IP ar...
